When i started my PC this morning , it started some “Startup repair tool” because windows couldn’t start. It applied some fixes and rebooted my PC. When windows start up, i noticed a notification sign on my avast Internet Security and when i opened the UI i saw a message : “Firewall is off: Turn on!”. When i try to turn on the firewall it says “Unable to start firewall”. I tried with restarting the computer, updating windows, but nothing helped. Should i re-install the program or do something else? And if i re-install my avast , will i be able to insert the licence again? Thanks in advance.
EDIT: I use Windows 7 , and avast program version is 8.0.1489
